315 MHz Wireless Transmitter Receiver Kit for Micro Controller
This kit comes with the MX-FS-03V transmitter module (3.5-12V), and the matching MX-05V receiver module (5V). The typical transmission range is 20-200m, dependingon the power supply, and with a straight quarter wave monopol antenna (l = /4)with 226mm length (just a piece of wire).Better antenna designs, like Yagi for example, can be good for a transmission distance up to some km.
Since the transmission range depends on the voltage supply, a 12V alkaline battery (as used for some remote controls) or 3-4 lithium button cells, connected in series, are recommended.
For Arduino, please download and install the “VirtualWire” library with example code included (download below).
